MQTT bridge for Denon AVR receivers.
Publish commands to denon/command and subscribe to denon/status. Transparently bridges I/O between a MQTT broker and the AVR's telnet interface.
Dead simple and ultra-lightweight method to intergrate a Denon AVR receiver into a home automation system. Should work with any Denon AVR receiver since it doesn't try to encaspulate the low-level protocol and make it user-friendly. It's intended to be used as a "set it and forget it" Docker container that just passes bytes to a MQTT subscriber where the real work happens. I wrote it because neither of the AVR nodes available in NodeRed to worked correctly with my Denon AVR-S760H and I wanted something more flexible than the Home Assistant intergration.
